The Barrington Town Hall is a former school building, of mass masonry construction, with portions constructed between 1930 and 1960. The town had a goal of reducing energy consumption and addressing existing IAQ issues occurring due to bulk water penetration at the exterior walls. BSC conducted a site visit and evaluation of the building, and made recommendations for directions to take in a capital renovation project. Although the town originally was considering an interior masonry wall insulation retrofit, a strong case was made for an exterior insulation overclad, due to advantages which include building durability, elimination of brick freeze-thaw risks, improved water control, and a change in aesthetics. BSC provided recommendations for roof, window, foundation, and mechanical system upgrades, and also evaluated and prioritized energy measures presented by others.
